Definitions
- the present invention belongs to the technical field of microporous crystalline materials of a zeolitic nature, useful as adsorbents, catalysts or catalyst components, for processes of transformation, adsorption and separation of organic compounds.
- Zeolites are microporous crystalline materials formed by a network of TO 4 tetrahedra that share all their vertices giving rise to a three-dimensional structure that contains channels and / or cavities of molecular dimensions. They are of variable composition, and T generally represents atoms with a formal oxidation state +3 or +4, such as Si, Ge, Ti, Al, B, Ga, ... When any of the T atoms has an oxidation state less than +4, the crystalline network formed has negative charges that are compensated by the presence in the channels or cavities of organic or inorganic cations.
- organic molecules and H 2 O can also be accommodated, so that, in general, the chemical composition of the zeolites can be represented by the following empirical formula: x (MiZ n XO 2 ): and YO 2 : z R: w H 2 O where M is one or more organic or inorganic charge cations + n; X is one or more trivalent elements; And it is one or several tetravalent elements, generally Si; and R is one or several organic cations.
- the chemical composition of a zeolite (as synthesized or after calcination) has a range characteristic of each zeolite and its method of obtaining.
- each zeolite with a specific system of channels and cavities, gives rise to a characteristic X-ray diffraction pattern, which allows them to be differentiated from each other.
- zeolites have been synthesized in the presence of an organic molecule that acts as a structure directing agent.
- Organic molecules that act as structure directing agents (ADE) generally contain nitrogen in their composition, and can lead to stable organic cations in the reaction medium.
- the mobilization of the precursor species during the synthesis of zeolites can be carried out in the presence of hydroxyl groups and basic medium, which can be introduced as hydroxide of the same ADE, such as tetrapropylammonium hydroxide in the case of zeolite ZSM-5.
- fluoride ions can act as mobilizing agents in zeolite synthesis, for example in the patent EP-A-337479 the use of HF in H 2 O at low pH is described as the mobilizing agent of silica for the synthesis of zeolite ZSM- 5.
- the present invention relates to a new microporous crystalline material of a zeolitic nature, identified as "ITQ-39 zeolite", and to its preparation process.
- This material both in its calcined and synthesized form without calcining, has an X-ray diffraction pattern that is different from other known zeolitic materials and, therefore, is characteristic of this material.
- the present invention relates firstly to a microporous crystalline material of a zeolitic nature that has, in the calcined state and in the absence of defects in its crystalline network manifested by the presence of silanoles, the empirical formula x (M 17n XO 2 ): y YO 2 : SiO 2 in which
- M is selected from H + , an inorganic cation of charge + n, and a mixture of both,
- X is at least one chemical element of oxidation state +3,

- d is a weak relative intensity between 0 and 20%
- m is an average relative intensity between 20 and 40%
- f is a strong relative intensity between 40 and 60%
- mf is a very strong relative intensity between 60 and 100%
- h means that this diffraction peak appears as a shoulder.
- microporous crystalline material of zeolitic nature after being calcined to remove the organic compounds occluded therein, has an X-ray diffraction pattern with at least 2, angle values (degrees) and relative intensities (VLo ) indicated in table II:
- Element X is preferably selected from Al, Ga, B, Fe, Cr and mixtures thereof.

- the material, as synthesized has an x-ray diffraction pattern with, at less, the values of angle 2 ⁇ (degrees) and relative intensities mentioned above (table I) and said material has in a calcined state an X-ray diffraction pattern with at least the values of angle 2 ⁇ (degrees) and relative intensities ( 1 / I 0 ) mentioned above (table II).
- the X-ray diffraction patterns of the ITQ-39 material have been obtained by the powder method using a fixed divergence slit of 1/4 ° and using the Cu radiation Ka. It should be noted that the diffraction data listed for this ITQ-39 zeolite sample as single or single lines, may be formed by multiple overlaps or overlapping reflections that, under certain conditions, such as differences in crystallographic changes, may appear as lines resolved or partially resolved. Generally, crystallographic changes may include small variations in the parameters of the unit cell and / or changes in the symmetry of the crystal, without a change in structure. Thus, the positions, widths and relative intensities of the peaks depend to some extent on the chemical composition of the material, as well as on the degree of hydration and crystal size.
- the ITQ-39 zeolite as synthesized presents an X-ray diffraction pattern as shown in Figure 2.
- This diagram is characterized by the values of angle 2 ⁇ (degrees) and relative intensities (1 / I 0 ) presented in the table

- the gel is heated for 7 days in steel autoclaves with an internal Teflon sheath at 15O 0 C in static.
- the solid obtained after filtering, washing with distilled water and dried at 100 0 C is ITQ-39.
- the gel is heated for 12 days in steel autoclaves with an internal Teflon cover at 135 0 C in static.
- the solid obtained after filtering, washing with distilled water and dried at 100 0 C is ITQ-39.
- the gel is heated for 14 days in steel autoclaves with an internal Teflon sheath at 15O 0 C in static.
- the solid obtained after filtering, washing with distilled water and dried at 100 0 C is ITQ-39.
- the gel is heated for 11 days in steel autoclaves with an internal Teflon sheath at 15O 0 C in static.
- the solid obtained after filtering, washing with distilled water and drying at 100 0 C is ITQ-39 and its X-ray diffractogram is shown in Figure 2.
- Figure 1 represents the organic cation in the presence of which the ITQ-39 zeolite is synthesized
- Figure 2 represents the most characteristic peaks of the X-ray diffraction pattern of the ITQ-39 material, as synthesized, obtained according to example 5.

Abstract
L'invention concerne une matière cristalline microporeuse de nature zéolitique, ITQ-39, caractérisée en ce qu'elle comprend, à l'état calciné et en l'absence de défaut sur son réseau cristallin manifestés par la présence de silanoles, la formule empirique : 5 x (M 1/n XO 2 ) : y YO 2 : SiO 2, M étant sélectionné entre H +, un cation inorganique de charge +n est un mélange des deux, X étant au moins un élément chimique d'état d'oxydation +3, Y étant au moins un élément chimique d'état d'oxydation +4 différent de Si, 10 x prenant une valeur comprise entre 0 et 0,3, les deux étant incluses, y prenant une valeur comprise entre 0 et 0,1, les deux étant incluses, et en ce que la matière, selon la manière de synthétiser, présente un patron de diffraction de rayons X, avec au moins les valeurs d'angle 2ϑ (degrés) et intensités relatives (I/I 0 ) affichées dans le tableau I. L'invention concerne aussi son procédé de préparation et son utilisation dans des processus de transformation, d'absorption et de séparation de composés organiques.
